2in Block & U-Bolt Kit

The ROUGH COUNTRY 2in Block & U-Bolt Kit is the foundation of any serious suspension lift installation, designed for truck and SUV owners who demand reliable ride height adjustment without compromising structural integrity. This kit addresses a fundamental need: safely and effectively raising your vehicle's center of gravity while maintaining proper axle alignment and suspension geometry. Whether you're building a daily driver with modest lift or preparing for aggressive off-road duty, this suspension component delivers the adjustability modern 4x4 platforms require.

The 2-inch block stack works by inserting precision-machined spacers between your axle and leaf springs, effectively raising the suspension without requiring spring replacement or extensive fabrication. ROUGH COUNTRY engineers the u-bolt configuration to maintain proper clamping force and prevent axle shift during acceleration, braking, or articulation—critical for vehicles that see trail time. The hardware is manufactured to OEM-equivalent tolerances, ensuring consistent fitment across production tolerances and reducing installation complications. Paired components distribute load evenly across the spring pack, minimizing stress concentration and extending component lifespan compared to budget aftermarket alternatives.

This kit suits owners of older leaf-spring-equipped trucks and SUVs seeking straightforward suspension modification without complete overhaul. The 2-inch height gain pairs well with coordinated driveline upgrades—extended CV axles, adjusted brake lines, and updated bump stops—to maintain proper geometry and ride quality. Installation typically requires standard hand tools and basic mechanical knowledge, though professional alignment after suspension work is strongly recommended to optimize tire wear and handling characteristics. Verify your vehicle's year, model, and axle configuration before ordering to ensure compatibility with this lift block system.
